The inner end of the shaft 27 has a beveled gear secured thereto as indicated by the numeral 29 which gear meshes with the beveled gear 30 secured to the lower endof the vertical shaft 21. The outer end of the shaft 27 carries the belt pulleys 32, and carried upon the supporting beams for the tank, forwardly of the same is a pair of beam members 33 designed "to be used as a supporting base for a power engine (not shown), from which power may be transmitted to the pulleys-32, as indicated in dotted lines in Figure 1.

The tank 7 has the wall thereof provided, adjacent the bottom, at the forwad part, with an outlet opening 34 and secured to the tank around this opening is an outlet 35.

Having thus described my invention, what I claim is:

In a road carpeting machine, a material carrying tank, a standard mounted in the tank, a shaft extending through the stand- .ard and through the bottom of the tank, a

base for the standard having an annular recess in its upper face, a sleeve surrounding the standard and having its lower end positioned in said recess, a cap overlying the upper ends of the standard and sleeve and secured to the sleeve and shaft, an upper pair and a lower pair of arms extending horizontally from the sleeve, the inner end portions of each pair of arms being arranged in contact with diametrically opposite sides of the sleeve, bolts passing through the arms of each pair in close proximity to the sleeve to secure the arms to the sleeve, vertical slats secured to the arms, and driving means connected to the 40 shaft. 7

In testimony whereof I afl'ix my signature.
